Metabolic Processes Unit Objectives
BIG IDEAS
1. All metabolic processes involve chemical changes and energy conversions.
2. An understanding of metabolic processes enables people to make informed choices with
respect to a range of personal, societal, and environmental issues.
Learning Goals
1. Analyse the role of metabolic processes in the functioning of biotic and abiotic systems.
2. Investigate the products of metabolic processes such as cellular respiration, protein and
lipid catabolism, fermentation, and photosynthesis
3. Demonstrate an understanding of the chemical changes and energy conversions that
occur in metabolic processes.
4. Assess the relevance, to your personal life, and to the community, of an understanding
of cell metabolism and related technologies
Learning Goals 2 and 3: Specific Success Criteria
Key Terms: Define the following terms and explain their relevance and significance to the unit:
o Energy carriers, glycolysis, Krebs Cycle/Citric Acid Cycle, electron transport chain,
oxidative phosphorylation, substrate-level phosphorylation, ATP synthase,
chemiosmosis, proton pump,
Aerobic Cellular Respiration

I can state the 1st and 2nd laws of thermodynamics and use these when describing the
transfer of energy in the cell.

I can list the four stages of cellular respiration, explain their relative locations, and
describe how each stage’s products feed into the next part of the pathway.

For Quizzes: I can describe, in detail, the molecular steps of each stage of C.R. including
molecules and energy both “used” and produced.

For the test: I can explain and compare the reactants and products (matter
transformation) of each stage.
I can explain the energy used and gained in each stage of cellular respiration, and
summarize the overall change in free energy.


I can explain the roles of both oxygen and the mitochondria organelle, in C.R.
Related Pathways

I can explain the anaerobic processes of lactic acid fermentation and ethanol
fermentation, and describe how they are connected to glycolysis.

I can explain the concepts of metabolic rate, lactate threshold, and VO2 max.

I can explain lipid and protein catabolism, when it occurs, and how it ties into cellular
respiration.
Photosynthesis
Define key terms and relate them to photosynthesis (here are some of them):
-
granum, thylakoid, lamellae, photosystem, photolysis, photoexcitation, chemiosmosis,
Calvin cycle, light and dark reactions etc….

I describe which organisms perform photosynthesis in their cells and describe any
differences in the process between these different organisms.

I can describe the stages of photosynthesis (in C3, C4, and CAM plants), explain their
relative locations, and describe how each stage’s products feed into the next part of the
pathway.

For Quizzes: I can describe, in detail, the molecular steps of each stage of
photosynthesis including the molecules and energy “used” or produced.

For the test: I can explain and compare the reactants and products (matter
transformation) of each stage.

I can explain the energy used and gained in each stage of photosynthesis, and
summarize the overall change in free energy.

I can explain the roles of CO2 and the chloroplast (and its parts), in photosynthesis.

I can compare the matter and energy transformations that occur during cellular
respiration, to those that occur in photosynthesis
o Include the roles of oxygen, C02, energy carriers, organelles such as mitochondria
and chloroplasts, and more… (see pg. 181)
